1 General introduction
1.1 Features
The TeraOhm 5kV Plus Tester is a portable battery / mains powered test instrument
intended for the testing of Insulation Resistance by using high test voltages of up to
5kV.
The instrument is designed and produced with the extensive knowledge and experience
acquired through many years of working in this sector.
Available functions offered by the TeraOhm 5kV Plus Tester:
High insulation resistance measurement up to 10 T
- Programmable test voltage from 250 V up to 5 kV, steps 25 V
- R(t) Graphs
- Programmable timer (1s up to 100 min)
- Automatic discharge of test object after completion of measurement
- Capacitance measurement
Insulation resistance measurement versus test voltage (step-up voltage test)
- Five discrete test voltages proportionately set within preset test voltage range
- Programmable timer 1 min up to 30 min per step
Polarization Index (PI), Dielectric Absorption ratio (DAR) and Dielectric Discharge
(DD) ratio
- PI = RINS (t2) / RINS (t1)
-
DAR = R

Withstanding voltage (DC) up to 5 kV
- Programmable ramp test voltage from 250 V up to 5 kV
- High resolution ramp (approx. 25 V per step)
- Programmable threshold current up to 5 mA
Voltage and frequency measurement up to 600 V AC/DC
A dot matrix LCD offers easy-to-read results and all associated parameters. The
operation is straightforward and clear to enable the user to operate the instrument
without the need for special training (except reading and understanding this Users
Manual).
Test results can be stored on the instrument. The new professional PC SW enables
straightforward transfer of test results and other parameters in both directions between
the test instrument and PC.
